Abstract
An apparatus, for reading the groove contour of spectacle frame rims, which includes first and second bearer structures for holding the spectacle frame, a first groove-contour-reading set, a second groove-contour-reading set, and a drive motor. Each of the first and second groove-contour-reading sets includes a first contact member for engaging the groove in one of the spectacle frame rims, a first guide member for guiding the movement of the contact member, and a reading member for reading the movements of the contact means. Further, the apparatus includes a drive motor for simultaneously driving the first and second contact members to thereby simultaneously read the groove contour in the two spectacle frame rims. Because the groove contours are simultaneously read, the apparatus reduces the time necessary to accurately measure the groove contour in each rim of a frame of spectacles.
